, oom-TESTER Fon SLOT-MACHINES.

Patented July 31, 1906.A

To all whom, it may concern.- .I

Be it known that I, MORGAN'D. SADTLER,

a citizen of the United States of America, and a resident of Baltimore city vand State of 5 Maryland, have invented certain new Vand.

useful Improvements. in Coin-Testers for Slot-Machines, of which the following is a specification. My invention relates to certain new and useful improvements in coin-testers adapted to be used in connection with coin-controlled machines of all types. j

The object of my invention is to provide a mechanism which will test each coin'dropped into the machine, and if it' is attempted to operate the machine by what is commonly called a slug the mechanism will detect this slug even though it is of the proper diarneter, thickness, and weight. By my invention I ltest each coin presented to the machine, and unless the'coin is of the proper size, diameter, thickness, and made of the proper metal the tester will not pass the coin in a manner to operate the coin-actuated mechanism to which the tester is applied.

Referring to the drawings, wherein I show one embodiment of'my invention for the pur-v pose of illustrating the same, and jwherein the same Iartis designated by the same reference-numeral wherever it occurs, Figure 1 is a perspective view of the coin-tester with a -coin in position to be tested. Fig. 2 is a central longitudinal section of the coin-tester,l Fig. 3 is a sectional view taken lon line 3 3 Aof Fig. 2. Fig. 4 is a top plan view of the tester, Ishowing how a slug of `lead or other soft metal is bent when placed in the tester. Fig. 5 isI av front view of one of thet heads, showing the 'slot therein.

In the embodiment of my invention shown, 1 designates a base portion on which the cointesting mechanism is mounted'.

2 3 are a pair of uprights extending up from .the base and provided Vin their `upper shaft 4v being mounted in the bearing of the upright 2 and the shaft 5 being mounted in the bearing of the upright 3. These shafts are in line with each other, with a space between their` adjacent ends.`

6 is a handle mounted on the outer end of theshaft 4, and 7 7 are stops carried by the A plate 8, secured to the base 1, the stops being ends 'with bearings for shafts 4 and 5., the v adapted to limit the rotation of thel crankhandle 6.

Mounted on the adjacent ends of the shafts 4 and 5 are the heads 9 and 10. 11 is a ,slot cut radially in the head 9 and extending from approximately the center to the periphery of thehead. This slot, as is best shown in Fig. 5,' has the inner portion of its'sides parallel fora' portion of the depth, and then the sides are beveled outwardly, as shown at 12, toward the periphery of the head, and the bottom 13 of theslot is inclined outward at the inner end to support acoin, as is shown in Fig. 2. The slot is formed with its side Walls flaring toward the periphery, so that the Aparallel,fand then they are beveled above the parallel portion, as shown at 15, the bevel being least at the center of the slot and invouter edges of the slot are' sector-shaped.

creasingon each side toward the periphery of the head, These slot's 11 and 14 form a pair ofj aws into which the coin to be tested is delivered. V 1

16 16 are a pair of notches placed on opposite sidesof the'head 10 and in line with the slot 14. 17 is a springsecured at one end to .a projection 18, mounted on the base 1, the

other end ofthe spring being slotted. 19 is an adjusting-screw tapped into the base 1 and passing through an opening in the end of the spring 17. The screw19 has projections 2O 20, one on each side of the spring, in order that the spring may be moved up or down by the said screw. 21 isa projection which is shown as formed by bending up a portion of the spring, the projection being adaptedto engage the depressions 16, formed in the head 10,. the spring being adapted to resist the initial turning movement of the head.

Located directly under the slots 11 and 14 is a coin-receiving slot 22, adapted to receive a coin from the slots after the machine hasbeen operated in a manner now to be described.

Supposing the parts to be in osition shown A I in Fig. 1 anda nickel to have een deposited in the slots 11 and 14 of the heads by being guided thereto by suitable runways or in any desired manner. The nickel having been deposited in the slot, the handle 6 is operated and turned until it strikes the upper stop 7. The turning of the handle will turn the head 9, and the nickel willbe clamped between the parallel sides of the slots 11 and 14. The projection 2l on the s ring 17, engaging one of the notches 16, willD resist the initial turnlng movement and tend to hold the head 10 from rotating until considerable force has been a plied. The metal of which the nickel is ma e is sufficiently soft to allow the `sides of the two slots to grip the metal and at the same time is sufficiently hard to prevent the nickel from being bent. The rotation of the handle 6 will consequently' 'c arry the nickel around a half-revolution until the `handle comes in contact with the upper stop- 7.

will enter the other notch 16 and stop the head 10 with its slot in line with the coin-receiving slot 22. The entrance of the projectlon 21 into the notch 16 carries the head 10 forward sufficiently to take the tension off the nickel, and consequently as the projection 21 enters the notch 16 the nickel will be released by the head. As the slot in the head 9' will at this time extend downward,

` the nickel is free to pass into the slot 21.

After the nickel is dropped into the slot the handle is released and the weight of the handle is suicient to return to its normal position 1n contact with the lower stop 7, with the slot in the head 9 extending upwardly in position to receive the next coin.

Ifa lead slugl of the pro er size to enter the slots 11 and 14' were ropped into the coin-tester instead of a nickel and it was attempted to operate the machine, the resistance of the spring 17 would be sufficient to cause the slug to be bent outof shape, as is shown in Fig. 4, the shape of the sides of the slots assisting in this operation, the bending continuing until the slot in the head 9 is revolved sufciently to cause the slug to become disengaged from the slot, and the slug will then drop out to one side and not pass into the coin-slot 22.

If an iron or steel slu of the proper size be dropped into the maclgiine, the sides of the slots will not take hold of the slug with a sufficient gri to carry the two parts of the head around; ut upon the turning of the head 9 the iron slug will sprin out of the slots and because of their bevele sides fall to one side ofthe coin-receiving slot.

If da slug .which is larger in diameter than required is dropped into the machine, it will 6 "be caught only by the upper edge of the quadrantroove and when that head is turned wil be twisted off its seat in that groove and will not turn the friction-held ead. If a slu which is too small be inserted, the same t 'ng will happen, but at the lower end of the quadrant-j aw( If a slug be Just before the handle 6 strikes the stop the projection 21 on the spring 17 lgripped at all and will consequently not turn the other head. If the slug be too soft, it will bend under the friction of the head and be thrown out.

It will thus be seen that I havedevised a mechanism which will revent the passage of anything but a coin o the proper character to operatethe machine-that is to say, it will prevent the use of lead or iron slugs, even though they be of the roper size and thickness, the metal of whic they are constructed causing the machine to cast them out and prevent them from being passedalong into the coin-slot.

While I have described what I believe to be the preferred form of my invention, I desire to have it understood that many changes may be made in the form and construction of the parts and that other elements may be substituted for those here shown and described for the purpose of carrying out the functions of the elements here shown and described without departing from the spirit of my invention and that where in the c aims I use the term means this term is to be understood as coverin all forms of mechanism 4which are capable o performing the function ascribed to the term in the claims.
